4 Claims.

This invention relates to improvements in a rotary cocoon lament feeding apparatus.

'I'he object of the invention is to provide an apparatus of the above character of improved and simplied construction in which the parts may be readily removed and replaced in case of damage thereto.

The accompanying drawing shows one example of the cocoon ber feeding apparatus according to the present invention.

Fig. 1 is a sectional elevation. Fig. 2 is a side View. Fig. 3 is a section through line 3-3 in Fig. 2. Fig. 4 is a sectional view through the rotary drum showing the embracing bars.

Fig. 5 is a plan showing the bar when detached. Fig. 6 is an elevation of the cylindrical axle for passing fibers.

Fig. 7 is an elevation of the anged body. Fig. 8 shows an elevation of the revolving drum.

Detailed explanations of the invention Referring to the drawing; near the front end of base plate I, the upper portion of a fiber passage pipe axle 2 is threaded therein. 'I'he pipe axle 2 is xed in suspended position, being held by nut 3.

A ber passage hole 4 is bored axially through the axle and in the lower portion of the ber passage hole 4, female screw threads are provided.

A anged body 6 with ber passage hole 5, is provided with male screw threads cut on the upper portion, which t into the female threads in the lower portion of the hole 4 mentioned above.

A rotary drum I loosely fits on the pipe axle 2 and its lower cylindrical portion is made to revolve round easily, being held by the anged body A V shaped channel 8 is provided in the drum 'I and in the channel thus provided, several Water holes 9 are bored and connect to the clearance space I0 in the bore of the drum 1.

Drum 1 is made of plastic materials such as Bakelite and the lower portion has the form of a cylindrical body I I. Surrounding the cylindrical body II, a circular groove I2 is cut around to allow embracing bars I3 and I4 to t therein, so as to be placed or replaced easily. 'Ihe metallic embracing bars are curved in their middle portions I5 so that they can embrace the cylindrical body II; the straight portions are held together u by soldering or other suitable means.

(Cl. 15J-3) Resiliency is given to the middle portions of the bars I3 and I4.

`An endless .transmission belt I6 is engaged in the V shaped channel 8 of the drum 1, by means of which the drum is driven. 5

The transmission belt I6 is constantly moistened on its surface by means of feed water and the water thus carried to the channel 8 and water holes 9 passes into the clearance space I0.

The ber passage pipe axle 2 is thus water 10 lubricated and at the same time the passage of transmission belt is made easy and smooth.

The embracing bars I3 and I4 can be simply and easily tted in position by merely springing the curved portions apart. In case the bars are 15 damaged, they can thus be easily replaced by spare ones. Therefore the disadvantage of entirely replacing the apparatus in case of a partial damage, is dispensed with.

The flanged body with fiber passage 5, is usual- 20 ly a portion easily damaged during the reeling operation but as this is simply screw connected in this case, it can be easily taken off.

Even in case the revolving drum is damaged, the drum can be easily taken off byrst unscrewing and removing the flanged body 6.

Thus the useless laborv and expense of removing the whole device from the base plate, is also dispensed with.V Thus according to the present invention, the parts composing the apparatus are separately formed and arranged so that they can be easily placed or replaced and therefore in case of transporting the apparatus, identical parts can be assembled and packed together and in case of transportations on large scale, the package volumes and expenses may be greatly saved.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States of America is:

1. A rotary ber feeding apparatus comprising a base plate, a ber passage axle detachably supported by said base plate, a drum rotatable on said axle, said axle having an axial passage extending throughout the entire length thereof, said drum being provided with a peripheral channel for receiving a driving belt and holes formed in the bottom of said channel and extending to the interior of the drum.

2. A rotary ber feeding apparatus comprising a base plate, a ber passage axle detachably supported by said base plate, a drum rotatable on said axle, said axle having an axial passage extending throughout the entire length thereof, a groove in said drum and bars resiliently embracing said groove.

3. A rotary ber feeding apparatus comprising a base plate, a ber passage axle detachably supported by said base plate, a drum rotatable on said axle, said axle having an axial passage extending throughout the entire length thereof, a groove in said drum and bars detachably mounted in said groove, said bars being resilient and adapted to be sprung apart to enable detachment and removal to and from said drum.

4. A rotary fiber feeding apparatus as claimed in claim 2 characterized in that said bars are formed of resilient material and have the medial portions thereof curved to embrace the groove in said drum and have the ends .thereof connected together whereby said medial portions may be sprung apart.
